Fix Hyper-V Time Synchronization Issue

by Weijie JIN on

We’re running Windows Server 2008 R2 for host and Windows Server 2008 R2 as a virtual machine using Hyper-V.

For some reason, the time synchronization doesn’t work well. No matter we disable the hyper-v time synchronization option on the host side or enable it. After the gap is more than 5 seconds, some issues will occur because of incorrect time.

We tried a lot and found there are several options:

  1. Restart the VM.
  2. Disable the time synchronization option in hyper v and enable it again.
  3. Write batch scripts in the VM to restart the time sync service.

We choose the last one because it can be automatically run:

1. Create a bat file as following:

net stop vmictimesync
net start vmictimesync

2. Create a scheduled task to run the script at 1:00am everyday:

It works pretty fine now. Smile
